content: update code in imports example

The important bit in this slide is the factored imports, and
the code example needs a reason to import two packages.

The `math.Sqrt` function is less likely to distract the reader
from the point than the `math.Nextafter`, which many people
are not familiar with.

Fixes golang/go#13180
